Kissing must be everywhere for the simple reason. Sexually, everyone has "mouth desire" because lips and tongue are very sensitive parts of human beings. When other senses are not fully developed, the baby will put something in his mouth when he catches it. In fact, they are not hungry, but use their tongues to make up for the lack of other senses. In addition to the mouth, other sexual organs of the human body (including nipples) are also very sensitive parts. So kissing is not taught, it is instinct. The French always like to say ". . . . Originated in France, China, too, stubbornly linked Cuju with modern football. In fact, it is natural to play with spherical things, even cats like to play with them. Doesn't football still originate from cats?
However, it is no problem that the kissing scene in costume drama takes place in your bedroom, but it is very unreal in the street. Ancient ethics absolutely resisted this kind of love in broad daylight.
